As of Fall 2003, real and complex analysis (which used to be separate exams) are combined into a single exam. It must be passed as a single unit. Students who passed one part in the past will be allowed to take just the other part to complete the exam.
Real Analysis
TOPICS Knowledge of material included in the undergraduate Analysis course (110.405-406) is assumed. This includes topics such as open and closed sets, compactness (incl. Heine-Borel theorem), continuity (incl. uniform continuity and the Arzela-Ascoli theorem). 1. Measure theory: Measurable sets and functions, outer measure, construction of Lebesgue measure. Lusin's theorem. Notions of convergence involving measure (pointwise a.e., convergence in measure). Egorov's theorem. 2. Lebesgue integral: Definition of $\int_X f(x) d \mu(x)$ and relation to the distribution function $\mu\{x: f(x) > t\}$. Fatou's Lemma and dominated convergence. $L^1(X, d\mu)$ as a normed space. Relation of convergence in $L^1$ to pointwise a.e. convergence and convergence in measure. Product measure and the Fubini theorem. Relation between Lebesgue and Riemann integrals. Riesz representation theorem concerning positive linear functionals on $C(X)$. 3. Lp spaces: Jensen, Holder and Minkowski inequalities. Completeness. Duality of $L^p$ and $L^q$ for $\frac{1}{p} + \frac{1}{q} = 1$. Bounded functionals, weak convergence on $L^p$. Uniform boundedness principle for $L^p(X, \mu)$. Approximation of $L^p$ functions on $\R^n$ by smooth functions. Weak compactness of unit ball in $L^p$. $L^2(X, d\mu)$. Hilbert space: Bessel inequality, orthonormal bases. 4. Fourier analysis: Fourier transform ${\mathcal F}$ on $L^1(\R^n)$ and $L^1(S^1)$ ($S^1$ = unit circle). Riemann-Lebesgue lemma. Plancherel theorem (${\mathcal F}$ as a unitary operator on $L^2(\R^n)$). Parseval inequality for ${\mathcal F}$ on $S^1$. Inversion formula. Convolution. Hausdorff-Young inequality.
